Abstract

Bei einem Hebezeug (1), das aus einem in einem zylinderartigen Gehäuse (11) eingesetzten und durch ein Lastseil (2) miteinander verbundenen Seilrädersätzen (21, 31) gebildeten Flaschenzug (10) besteht, wobei ein Seilräder­ satz (21) ortsfest angeordnet und der andere Seilrädersatz (31) in einem von Druckmittel beaufschlagbaren Kolben (15) gehalten ist, ist diesem eine Bremseinrichtung (41) zugeord­ net, mittels der die Verstellbewegung des Kolbens (15) bei Überschreitung eines vorgegebenen Höchstwertes abbrems­ bar ist. Die mit einem der Seilrädersätze (21) zusammenwir­ kende Bremseinrichtung (41) besteht hierbei aus einer über ein Gewinde (45, 47) trieblich mit einer der Seilrollen (23′) verbundenen in Achsrichtung begrenzt verschiebbaren Schwungscheibe (42) und einem Gegenlager (Deckel 12), die auf den einander zugekehrten Stirnseiten mit Bremsflächen (43, 53) versehen sind. With a hoist (1) that consists of one in one cylindrical housing (11) used and by a Load rope (2) interconnected sets of rope wheels (21, 31) formed pulley (10), wherein a rope wheels set (21) and the other set of rope wheels (31) in a piston (15) which can be acted upon by pressure medium is held, this is associated with a braking device (41) net, by means of which the adjusting movement of the piston (15) Decelerate when a specified maximum value is exceeded is cash. Which cooperate with one of the sets of cable wheels (21) kende braking device (41) consists of an over a thread (45, 47) drivingly with one of the rope pulleys (23 ′) connected axially displaceable Flywheel (42) and a counter bearing (cover 12), the on the facing end faces with braking surfaces (43, 53) are provided.

Auf diese Weise wird erreicht, daß durch die Verstellge­ schwindigkeit des Lastseiles (2) selbsttätig die Bremseinrich­ tung (41) ausgelöst wird, in dem bei einer zu raschen Beschleunigung des Kolbens (15) die an der Seilrolle (23′) anliegende Schwungscheibe (42) nicht mehr mitgenommen wird und sich somit gegenüber dieser verdreht. Durch eine Relativdrehung wird jedoch über das Gewinde (45, 47) eine Axialverschiebung der Schwungscheibe (42) hervorgerufen, so daß diese an dem Gegenlager (Deckel 12) zur Anlage kommt und somit die Seilrolle (23′) und das über diese geführte Lastseil (2) abgebremst werden. Ein Hochschnellen des Lastseils (2) wird dadurch zuverlässig vermieden. In this way it is achieved that through the adjustment Speed of the load rope (2) automatically the brake device device (41) is triggered in which to snap at one Acceleration of the piston (15) on the rope pulley (23 ′) adjacent flywheel (42) is no longer taken is and thus rotated relative to this. By a However, relative rotation is a via the thread (45, 47) Axial displacement of the flywheel (42), so that these on the counter bearing (cover 12) to the system comes and thus the pulley (23 ') and this guided load rope (2) are braked. A blast the load rope (2) is reliably avoided.
